1. x[n] contains 128-point samples obtained through sampling continuous-time signal x (t) with sampling period T = 0.1 sec. X[k] (k = 0,1,.,127) represents 128-point DFT of x[n]. Then, DFT index k = 32 corresponds to @=_ _rad in X(e), DTFT of x(t), and corresponds to Ω= rad/s in X (22), CTFT of x(t).

Question
1. x[n] contains 128-point samples obtained through sampling continuous-time signal x (t) with sampling period T = 0.1 sec. X[k] (k =0,1,.,127) represents 128-point DFT of x[n]. Then, _rad in X(el), DTFT of x(t), and corresponds DFT index k = 32 corresponds to @=. to Ω- _rad/s in X (2), CTFT of x(t).
